Briefly, this error occurs when Elasticsearch is unable to delete temporary files created during a job execution, possibly due to insufficient permissions or a locked file. To resolve this, ensure that the Elasticsearch process has the necessary permissions to delete files in the directory. If the files are locked, identify the process locking the files and terminate it. Also, consider increasing the disk space if it’s running low, as this could prevent file deletion. Regularly cleaning up old or unnecessary files can also help prevent this issue.
